Glue bottom bulk container

Abstract

An eight sided flexible intermediate bulk container formed from a substantially flat bottom wall of woven fabric with a first side, a second side, a peripheral edge surrounding the first and second side, and an octagonal horizontal cross sectional area. The container is further formed from a tubular sidewall blank of a woven fabric with a sidewall, an exterior side, an interior side, a first end, a second end, a first portion of the sidewall proximate to the second end, the first portion being cut in a sawtooth configuration including a plurality of adjacent triangular shaped flaps, a second portion of the sidewall proximate to the second end, and an interior cross section of size and octagonal shape for receiving the bottom wall. The bottom wall is positioned inside the first portion of the tubular blank perpendicular to the longitudinal axis of the tubular blank, wherein the peripheral edge of the bottom wall contacts the interior sidewall a predetermined distance from the first end, and the first side of the bottom wall is disposed toward the first end of the blank and the second side of the bottom wall is disposed toward the second end of the blank. The adjacent triangular shaped flaps of the first portion of the side wall blank are folded toward the bottom wall with the interior side of the triangular shaped flaps being affixed with adhesive to the first side of the bottom wall.

I claim: 
     
       1. An eight sided flexible intermediate bulk container comprising: a substantially flat bottom wall of woven fabric having: a first side,   a second side,   a peripheral edge surrounding the first and second side, and   an octagonal horizontal cross sectional area;     a tubular sidewall blank of woven fabric having: a sidewall,   an exterior side,   an interior side,   a first end,   a second end,   a first portion of the sidewall proximate to the first end, said first portion being cut in a sawtooth configuration including a plurality of adjacent triangular shaped flaps,   a second portion of the sidewall proximate to the second end, and   an interior cross section of size and octagonal shape for receiving the bottom wall;     said bottom wall positioned inside the first portion of said tubular blank perpendicular to the longitudinal axis of the tubular blank, wherein the peripheral edge of the bottom wall contacts the interior sidewall a predetermined distance from the first end, and having the first side of the bottom wall disposed toward the first end of the blank and the second side of the bottom wall disposed toward the second end of the blank; and   said adjacent triangular shaped flaps of the first portion of the side wall blank being folded toward the bottom wall with the interior side of said triangular shaped flaps being affixed with adhesive to the first side of said bottom wall.
